I've followed instruction on community forum and method help. Even uninstalled and reinstalled plug-in. Using Comcast Business Class exchange for email, pulling it into Outlook. I think something is wrong on the Setup Default screen. What should be in the Internal Outlook Exchange Domain @. Then when I click on appointments or appontments detail tab (still in setup) I get: Method API response login failed. This is the same error I get when I click on "Add to Method" anywhere in Outlook. Any assistance would be greatly appreciated!!!
